IMPROVEMENT IN WATER-ELEVATRS.

Specification forming part of Letters Patent No. 44,789, dated October 25, 1.864.

'To all whom it may 'concern y Be it known that I, JONATHAN DEARBORN, of Seabrook, VVin the county of Rockingham Avand State of New Hampshire, have invented an Improved Apparatusfor Elevating Water from a Well or elsewhere; and I do hereby declare the saine to be fully described in the following specification, and represented in the accompanying drawings, ot' which- Figure l is a' side View, Fig. 2 ,a front ele- A sation, Fig. 3 a longitudinal section, and Fig. 4 a transverse section, of it.

In the drawings, A A denote a series of buckets, each of which is placed between two endless chains, B B. To each of the said chains there are two supportingwheels, C l), the chain working around them or being extended about thein, as shown in the drawings.

The v`lower of the wheels-wiz., D-of each 'chain is circular,and basa flange, w. fire-np per, wheel, C, is made' of two circular disks, b c,`

united by a series of cross-bars, e e e, Src., and

a hub, ji vThe two upper wheels are applied ona shaft, g, and one of them has a notch, s,

,in its' periphery, such notch being for the reception of the bucket-supports, to be here- .inat'ter explained.

made of a strip of metal bent in the form in Each link of the chain is longitudinal section, as shown in Fig. 5\'iz.,

brace'pand s'erre'to hold the adjacent parts in should be about equal to the length of` 'each --link of thechain, and" `there should be a re! 'cess or space between each two connectingv ,bars suilcient to ,receiye the arch or .braeet' of a"lvink1while the said ,link may'be'snpported ,attive/periph ery.

" E- Ch'bucket, is connected tothe two chains by means off-around rod,"n,which' goes' spout or chute.

through the bucket and has its ends 'inserted I in two boxes, o o, aftixed to the two chains. Furthermore, each bucket is loaded on its lower end by a weight, p, affixed thereto, the

same being to cause the bucket to assume an upright position limmediately after having been tipped or turned over so as to cause its contents to be Vdischarged into a spout or chute, E.

For the purpose of tipping the bucket such bucket is provided with an arm, q, which eX- tends up from itin manner as shown inthe drawings. cranked shaft, r, `which projects from the While the bucket is being raised upward the arm will be caught by the trpper, which will so act on it as to turn the bucket in a manner to cause its contents to be dischargedl from the bucket and into the chute. Unrevolving the shaft ot the spreek et-wheels C O such wheels will be put in' motion simultaneously, and will move the chains in such a manner as to cause one or more of the buckets to be raised up while the other or others may be descending, and if the lower Wheels are placed in water such water will be raised by the buckets up to and discharged into the spout or chute.

0n each bucket-rod u Vthere are two sinkers, Wheels, or weights, s' s', which are arranged 'o opposite sides of the bucket and so as to co ne between it and the sprocketwheels while the bucket may be passing them. The objectof these rotary'sinkers (which freely rotate on the rod is not only to keep the bucket from contact with the, Wheels and l getting clogged by any matter which may get between thebucket and either of the wheels, but to sink the chain well in the notch while it may be passing underneath the lower wheel,

D. Furthermore, these weightsl often enable the said lower wheel to be dispensed with I do not claim a waterelevator consisting of a series'ot' buckets, one or. incre endless chains, and one or more supporting-wheels; nor do VI claim the tripperand the arm as applied to the chute and the bucket to; operatev in manner as hereiubeforc described. ,l

What I do claim is 1. The improved chain audits sprocketwheel as constructed in manner and to-operateV asspecified, the chain undersuch construction having an. arch orV currfed'brace to It operates with a tripper orv made with recesses or spaces between its chainliik bearings and for the reception of such arches or braces of such links, as described.

2. The combination of the circular Wheel D With the chain constructed with arches or braces to its links, and with the sprocket-wheel made so as to support the links at their junetions, nnd with recesses or' spaces for receiving the link-arches in manner as specified.

3. vThe application of each bucket to the chains by 'means of a. rod .running through the bucket and supported in bearings applied. to the chains, as described.

4. The arrangement and combination of the sinkers s s withthe bucket, the chains, the bucket-rods, find the sprocketwheels,`asde scribed.
